Description:
Iron-air battery platform for rare-earth-free, non-flammable, and cost-effective long-duration energy storage.
Key Highlights:
Grants Received: ~$0.3M
Funding Raised: ~$0.7M
Core Problem Statement
Structural solar and wind intermittency creates multi-day flexibility gaps that lithium-ion and other short-duration storage solutions cannot economically bridge at grid-scale.
Solution Overview
An iron-air battery platform using rare-earth-free, non-flammable aqueous chemistry. It features a proprietary iron-particulate bed architecture that suppresses hydrogen evolution and surface passivation, delivering lab-validated 100–145 hour continuous discharge cycles at a significantly lower capex than lithium-ion.
Strategic Engagement Opportunities
Karetic Energy's iron-air modular battery offers utility corporates a pilot-ready long-duration storage solution. There are opportunities to explore integration with industrial microgrids and renewable farms to bridge multi-day intermittency gaps.
